19 * The version identifier for this Serializable class.
\r
20 * Increment only if the <i>serialized</i> form of the
\r
23 private static final long serialVersionUID = 1L;
\r
26 * An integer that describes the kind of this token. This numbering
\r

\r

\r
47 * A reference to the next regular (non-special) token from the input
\r
48 * stream. If this is the last token from the input stream, or if the
\r
49 * token manager has not read tokens beyond this one, this field is
\r
50 * set to null. This is true only if this token is also a regular
\r
51 * token. Otherwise, see below for a description of the contents of
\r
57 * This field is used to access special tokens that occur prior to this
\r
58 * token, but after the immediately preceding regular (non-special) token.
\r
59 * If there are no such special tokens, this field is set to null.
\r
60 * When there are more than one such special token, this field refers
\r
61 * to the last of these special tokens, which in turn refers to the next
\r
62 * previous special token through its specialToken field, and so on
\r
63 * until the first special token (whose specialToken field is null).
\r
64 * The next fields of special tokens refer to other special tokens that
\r
65 * immediately follow it (without an intervening regular token). If there
\r
66 * is no such token, this field is null.
\r
68 public Token specialToken;
\r
71 * An optional attribute value of the Token.
\r
72 * Tokens which are not used as syntactic sugar will often contain
\r
73 * meaningful values that will be used later on by the compiler or
\r
74 * interpreter. This attribute value is often different from the image.
\r
75 * Any subclass of Token that actually wants to return a non-null value can
\r
76 * override this method as appropriate.

\r
107 public String toString()
\r
113 * Returns a new Token object, by default. However, if you want, you
\r
114 * can create and return subclass objects based on the value of ofKind.
\r
115 * Simply add the cases to the switch for all those special cases.
\r
116 * For example, if you have a subclass of Token called IDToken that
\r
117 * you want to create if ofKind is ID, simply add something like :
\r
119 * case MyParserConstants.ID : return new IDToken(ofKind, image);
\r
121 * to the following switch statement. Then you can cast matchedToken
\r
122 * variable to the appropriate type and use sit in your lexical actions.
